Types

type Builder

type Builder interface {
	OnData(bid db.BucketID, value []byte) error
	UnresolvedCount() int
	ResolvedCount() int
	Requests() RequestIterator
	RequestData(id db.BucketID, key []byte, requester DataRequester)
	Database() db.Database
	Flush(write bool) error
}

func NewBuilder

func NewBuilder(dbase db.Database) Builder

func NewBuilderWithRawDatabase

func NewBuilderWithRawDatabase(dbase db.Database) Builder

type CopyContext

type CopyContext struct {
	// contains filtered or unexported fields
}

func NewCopyContext

func NewCopyContext(src db.Database, dst db.Database) *CopyContext

func PrepareCopyContext

func PrepareCopyContext(src db.Database, dst db.Database) *CopyContext

PrepareCopyContext prepares CopyContext for copying src to dst. If dst comes from another CopyContext, then it returns the original one for tracking progress properly.
